D'Addario Violin Zyex Set 4/4 Size Light (Silver D), DZ310S-L5JaneNovember 17, 2009Have used the Zyex before (and liked them) but not the light weight. Was not pleased with them particularly for the solo performance I was trying them out for. I will give them another whirl for Jazz playing. Am curious if the lighter weight would be good for this context.
